The patented X-Tractor design boosts overall performance by finely tuning the exhaust between the factory headers and mufflers. Don't be misled by imitations.

The Torque Monster has been quoted as "making more low end torque than the X-Tractor." The chart below puts this myth to rest. The original, one and only patented X-Tractor increases performance and efficiency throughout the rev range. Testing of the X-Tractor and Torque Monster was independently performed by Sabin Performance of Texas.
